Ultra-High Vacuum Thin-Walled Glass Cell
The MP-TWC-20-20-65 is a high-performance glass vacuum cell specifically designed for ultra‑high vacuum (UHV) quantum experiments, providing excellent optical access for cold atom, quantum optics, and precision measurement applications. Manufactured from Borofloat® 33 borosilicate glass and leveraging AVR Optics (Infleqtion)’s proprietary glass‑to‑metal sealing technology, the cell is assembled without epoxy or glass frit. This approach ensures outstanding vacuum performance while substantially reducing outgassing rates, making it highly suitable for long‑term, stable UHV systems.
Product features:Excellent optical access;Ultra‑high vacuum compatibility;Contamination‑free sealing process;High reliability
Part Number:MP-TWC-20-20-65
Application area:Cold atom experiments | Quantum computing | Quantum sensing | Precision measurements
